Vance & Hines PCX Shortshots Staggered Exhaust For Harley Softail (2018–2024)
Iconic Shorty Drag-Pipe Styling Powered by Power Chamber Exhaust (PCX) Technology
Upgrade the look, performance, and acoustic profile of your Milwaukee-Eight Softail with the Vance & Hines PCX Shortshots Staggered Exhaust System. Engineered specifically for 2018 through 2024 Harley-Davidson Softail models, this full system features Vance & Hines’ revolutionary PCX™ (Power Chamber Exhaust) technology. Integrating high-flow chambered catalytic converters directly inside the header collectors, PCX boosts low-end torque while maintaining clean emissions and delivering that signature hot-rod exhaust bark.
Featuring full-coverage 220-degree heat shields over stepped 1-3/4″ to 2-1/8″ header pipes, PCX Shortshots eliminate heat discoloration (blueing) while delivering a clean, aggressive stance that complements both modern and classic Softail builds.

PCX Technology: High-Flow Performance Engine Optimization
Chambered Catalyst Flow & Torque Gains
Traditional drag pipes often sacrifice crucial low-end torque due to excessive loss of exhaust backpressure. Vance & Hines solves this with PCX™ technology. By placing high-flow, low-restriction chambered catalysts inside the collectors, exhaust pulses are scavenged efficiently. This maintains broad low-to-mid range torque across the 2,000 to 4,000 RPM powerband without restricting top-end horsepower gains on Milwaukee-Eight 107ci, 114ci, and 117ci engines.
Dyno-Tested Performance Highlights
- Torque Improvements: Substantial low-end torque increase over standard open drag pipes.
- Clean Emissions & Thermal Efficiency: Internal catalysts reduce exhaust emissions while generating a smooth, deep hot-rod tone.
- Stage 1 Synergy: Maximum power gains when paired with a high-flow air cleaner and ECU tuning.

Step-by-Step DIY Installation Guide
Installing PCX Shortshots Staggered on your Softail takes approximately 60–90 minutes with standard shop tools.
Required Tools & Supplies
- 3/8″ Ratchet with 1/2″, 7/16″, and 9/16″ sockets
- Torque wrench (ft-lbs and in-lbs)
- O2 sensor wrench or 22mm / 14mm open-end wrench
- New exhaust port gaskets (Vance & Hines #22899 or OEM #65324-83B recommended)
- Rubbing alcohol and microfiber towel
Step 1: Removal of Factory Exhaust System
Disconnect your motorcycle battery. Unplug the front and rear O2 sensor wires from the frame harness. Unbolt the exhaust flange nuts at the cylinder heads and remove the rear frame mounting bolts. Carefully lift the complete stock exhaust system away from the motorcycle.
Step 2: Installing Port Gaskets & O2 Sensors
Remove the old exhaust port gaskets and install fresh tapered metal mesh gaskets. Unscrew the original O2 sensors from the factory exhaust, apply anti-seize to the threads (avoiding the sensor tip), and install them into the 18mm/12mm adapter ports on the PCX headers.
Step 3: Mounting the Headers & Heat Shields
Position the front and rear header pipes loosely into the exhaust ports, securing flange nuts finger-tight. Install the heavy-duty frame mounting bracket provided in the kit. Slide the full-coverage heat shields onto the headers using hose clamps. Align the staggered muffler tips evenly.
Step 4: Torque Specs & Degreasing Wipe-Down
Torque header flange nuts evenly to 100–120 in-lbs. Tighten frame mount bolts to 18–22 ft-lbs.
CRITICAL WARNING: Wipe down the entire chrome or matte black surface with rubbing alcohol prior to starting the engine. Fingerprints or grease left on the metal will permanently bake into the finish!
EFI Fuel Tuning Recommendations
Because the PCX Shortshots Staggered system drastically improves exhaust flow compared to restrictive stock pipes, reflashing the ECU is strongly recommended. Installing a tuner like the Vance & Hines Fuelpak FP4 ensures proper air-fuel ratios, eliminates deceleration popping, and prevents running lean.
Frequently Asked Questions
Are quiet baffles available for PCX Shortshots Staggered?
Yes. Optional quiet baffles (Part #21869) are available to tone down overall volume by 2 to 3 dB while retaining a deep, aggressive exhaust note.
Will these pipes fit Softail models with passenger footpegs or saddlebags?
Yes. The kit includes relocation brackets for passenger footpegs. However, due to the short staggered design, extended saddlebags may require high-clearance support brackets.
